Class MetalDynamicParallelism

Namespace

DotCompute.Backends.Metal.Execution

Assembly

DotCompute.Backends.Metal.dll

Metal dynamic parallelism manager for nested kernel execution. Supports kernels launching other kernels using Metal 3's indirect command buffers. Equivalent to CUDA dynamic parallelism for recursive/hierarchical algorithms.

Methods

CreateIndirectCommandBufferAsync(nint, int, CancellationToken)

Creates an indirect command buffer for dynamic kernel launches. Metal 3 feature for GPU-driven work submission.

public Task<nint> CreateIndirectCommandBufferAsync(nint device, int maxCommands, CancellationToken cancellationToken = default)

Parameters

device nint

maxCommands int

cancellationToken CancellationToken

Returns

Task<nint>

Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

public void Dispose()

EncodeNestedKernelAsync(nint, nint, int[], int[], CancellationToken)

Encodes a nested kernel launch in the parent command buffer.

public Task EncodeNestedKernelAsync(nint parentBuffer, nint childKernel, int[] gridSize, int[] threadgroupSize, CancellationToken cancellationToken = default)

Parameters

parentBuffer nint

childKernel nint

gridSize int[]

threadgroupSize int[]

cancellationToken CancellationToken

Returns

Task

ExecuteWithDynamicParallelismAsync(KernelDefinition, KernelDefinition[], int, CancellationToken)

Executes a parent kernel with dynamic child kernel launches. Supports multi-level nesting for hierarchical algorithms.

public Task ExecuteWithDynamicParallelismAsync(KernelDefinition parent, KernelDefinition[] children, int maxNestingLevel = 3, CancellationToken cancellationToken = default)

Parameters

parent KernelDefinition

children KernelDefinition[]

maxNestingLevel int

cancellationToken CancellationToken

Returns

Task

GetMetrics()

Gets dynamic parallelism execution metrics.

public DynamicParallelismMetrics GetMetrics()

Returns

DynamicParallelismMetrics
